Bioinformatics course

This course teach how to interpret and understand the results of bioinformatic analyses. Even if they do not use the tools, all molecular biologists need to understand the meaning of bioinformatics results. It is important to speak the same language, and be aware of the key aspects that can lead to the experiment's success or failure.

Rules for writing

Scientists are writers. Papers, reports, projects, and so on. It is important to write clearly to be understood. If you write in manuscript, you need to use a good calligraphy. There are also rules for typing a text in the computer. Here are these basic rules.

Calculating π as Archimedes did

Every 14 of March, mathematical inclined people around the world publishes articles about π, circles and diameters. Here we use the tools developed in previous posts to calculate some digits of π.

The secret number, the golden number, and the Babylonian method to find them

Now that we know how to calculate numbers with a lot of decimals, let's look for the number that Pythagoras does not want you to know, and for the number made of gold.

Ten thousand digits of 𝑒

Your computer is better than your dad's computer. It can easily do things that old computers had hard time doing. We just need to think it well and explain the steps one by one.

Methodology of Scientific Research

This course focus in theoretical and practical aspects of doing science. In particular we learn how to design good experiments that can create high-impact knowledge. This year we will focus on gene expression experiments.

I'm on Chilean TV!

Among the several shows in Chilean TV, there is one about Chilean expats. It is called “Siempre hay un Chileno” (that is “There is always a Chilean”). The name comes from the idea that, wherever in the world you go, there will alway be a Chilean migrant.

An easy way to transform your R script into a nice report

Let’s say we have written an R script and we want to include some comments about it. For example, we want to discuss the meaning of the results. It is easy to make a report from your R script, with the simple changes we discuss here.

Hard problems

Some students argue that the exercise “find the largest value” is too hard. This raises the question “What do we mean by hard problem”? The answer teach us important things about life, the universe, and everything.

Should I learn Turkish? What is best for the University?

Some people ask me why I do not learn Turkish. It is a good question. For sure, it will be good for me. I would be able to speak about football with the butcher, discuss politics with my father-in-law, and read my collection of Matematik Dünyası magazine. But, what is best for our University?

The Biologist Toolbox: Simulating Systems on the computer

Once we have a description of a system, and a nice drawing to represent it, we can answer some interesting questions. The first question is usually “what will happen?” In other words, we usually want to know what is the behavior of the system.

The Biologist Toolbox: Drawing Systems

Can we represent a complex system in a simple and easy-to-understand way that is still realistic enough to be useful? The graphical representation that we discuss here, based on Petri nets, can be used to summarize a dynamical system and can easily be translated into a simulation.

Keep your mind sharp on August

Why do rich kids learn more than poor kids? According to some research, the “achievement gap” between kids of high-income and low-income families is not that rich kids learn more, but that they forget less in the summer holiday. Following this idea, I propose a couple of challenges to keep your mind active during the holidays, and maybe win a nice book.

My Professor got an International Prize

One of my professors got an international award. He had already won the most prestigious national recognitions in Science. Now he became global. This gives me the opportunity to start a series of posts about my world-class professors and their international achievements.
